| 20120059491 | CARRYING AUXILIARY DATA WITHIN AUDIO SIGNALS - A system for inserting auxiliary data into an audio channel that carries an audio signal includes a modulator configured to convert an auxiliary data signal into a modulated auxiliary data signal that has a passband within the audio channel's passband. The system for inserting auxiliary data into an audio channel that carries an audio signal further includes summing means configured to combine the modulated auxiliary data signal and the audio signal into a combination signal to be carried in the audio channel. | 03-08-2012 |
| 20100145713 | ADDING ADDITIONAL DATA TO ENCODED BIT STREAMS - A method of adding additional data to encoded bit streams may include receiving a signal containing an encoded data frame, where the encoded data frame includes a plurality of data blocks. The method may further include transforming the encoded data frame into a modified encoded data frame by inserting at least one additional data block between a synchronization information block and an error check block, where the at least one additional data block includes the additional data, and modifying data in at least one of the synchronization information block and the error check block to account for the inserting of the at least one additional data block. | 06-10-2010 |
